MODULAR ARITHMETIC

About the topic modular arithmetic

Modular Arithmetic is also one of the topics which plays a major
role
in quantitative aptitude test. It is bit difficult to score marks in
competitive exams without knowing the shortcuts related to modular arithmetic, We have already learned this topic in our
lower
classes.Even though we have been already taught this topic in our lower
classes, we need to learn some more short cuts which are being used to
solve the problems in the above topic.

The only thing we have to do is,
we need to apply the appropriate short cut and solve the problems in a
limited time. This limited time will be one minute or less than one minute in most of
the competitive exams.

Why is this topic needed?

Students who are preparing to improve
their aptitude skills
and those who are preparing for this type of competitive test must
prepare this
topic in order to have better score. Because, today it is bit difficult
to score marks in competitive exams without knowing to solve word problems on this topic. Whether a person
is going to write placement exam to get placed or a student is going to
write
a competitive exam in order to get admission in university, they must be shortcuts related to month arithmetic, day clock arithmetic and hour clock arithmetic. This is the reason for why people must
study
this topic.

What is the advantage of this topic?

As
we mentioned in the above paragraph, a person who wants to get placed in a
company and a students who wants to get admission in university for higher
studies must write competitive exams like placement test and entrance exam. To
meet the above requirement, it is very important to score more marks in the
above mentioned competitive exams. To score more marks, they have to prepare
this topic. Preparing this topic would definitely improve their marks in the
above exams. Preparing this topic is not difficult task. We are just going to
remember the stuff that we have already learned in our lower classes

How can students apply shortcuts in modular arithmetic?

Students
will learn, how and when they have to apply shortcuts to solve the problems which are related to this topic. Apart from the regular
shortcuts, students can learn some additional tricks in this topic. Already we
are much clear with the four basic operations which we often use in
math. They
are addition, subtraction, multiplication and division. Even though we
are much
clear with these four basic operations, we have to be knowing some more
stuff
to solve the word problems on this topic which are being asked in competitive exams.
The stuff which I have mentioned above is nothing but the tricks and
shortcuts
which need to solve the problems in a very short time.

Shortcuts we use to solve the problems

Short cut
is nothing but the easiest way to solve word problems on this topic. In competitive exams, we will have very limited
time to solve each problem. Then only we will be able to attend all the
questions. If we do problems in competitive exams in perfect manner with
all
the steps, it will definitely take much time and we may not able to
attend the
other questions. So we need some other way in which the problems can be
solved in
a very short time. The way we need to solve the problem quickly is
called as
shortcut.

In modular arithmetic, we are going to learn solving word problems in the following three sub topics. Please click the below links to get concept and problems with solutions.
